Overview of the GENEROUS Model
The Centers for Medicare & Medicaid Services (CMS) has unveiled a groundbreaking drug payment initiative designed to transform prescription medication affordability for millions of Americans. The GENErating cost Reductions fOr U.S. Medicaid (GENEROUS) Model represents a significant policy shift in how the nation’s largest public health insurance program negotiates pharmaceutical pricing.
Scheduled to launch in January 2026, this voluntary five-year program will enable participating states to purchase prescription medications at prices comparable to those paid in other developed nations. The initiative directly addresses the growing concern over prescription drug costs, which have consistently outpaced inflation and strained state Medicaid budgets nationwide.
This announcement follows several Trump administration initiatives targeting high pharmaceutical costs, including the Most Favored Nation (MFN) executive order and subsequent pricing agreements with major pharmaceutical manufacturers such as Pfizer, AstraZeneca, Novo Nordisk, and Eli Lilly and Company.
Understanding the Drug Pricing Initiative
Key Program Features
CMS Administrator Mehmet Oz, MD, emphasized the historic nature of this commitment: “Under the leadership of President Trump and Secretary Kennedy, CMS is making a historic commitment to driving down the cost of drug prices and ensuring Americans have access to life-saving medications. The GENEROUS Model will help ensure state Medicaid programs are paying a fair and reasonable price for prescription drugs—furthering our efforts to preserve funds for our most vulnerable.”
The GENEROUS Model builds upon existing frameworks, including the Medicaid Drug Rebate Program (MDRP), which provides manufacturer rebates to states in exchange for coverage of outpatient medications. Additionally, it incorporates lessons learned from the Cell and Gene Therapy Access Model, which facilitates CMS-negotiated manufacturer agreements to expand access to advanced therapies for Medicaid beneficiaries.
The program introduces Most Favored Nation (MFN) drug pricing principles to Medicaid, allowing states to benefit from international price benchmarking. This approach aims to eliminate the significant price disparities that currently exist between the United States and other developed countries for identical medications.
Implementation Process and Timeline
How Rebates Work
Under the GENEROUS framework, participating pharmaceutical manufacturers will adjust their pricing through supplemental rebates provided to participating states. This mechanism ensures that Medicaid programs pay prices aligned with international standards rather than the traditionally higher U.S. market rates.
The operational structure involves states invoicing manufacturers directly for these supplemental rebates. CMS will maintain oversight responsibilities, monitoring payment accuracy and ensuring compliance with negotiated terms. Importantly, rebates secured by states will be shared with CMS through reductions in the federal share of Medicaid payments, creating a collaborative cost-savings mechanism.
CMS and participating manufacturers will jointly negotiate standardized coverage criteria, ensuring transparency and consistency across state programs. Participating states will then implement these standardized criteria, creating uniformity in medication access policies while maintaining the negotiated pricing advantages.
Financial Impact on Medicaid Spending
The financial stakes are substantial. In 2024, total gross Medicaid spending on prescription drugs exceeded $100 billion—representing a $10 billion increase from 2022 figures, according to CMS data. After accounting for existing manufacturer rebates, net Medicaid pharmaceutical spending reached $60 billion.
CMS Innovation Center Director Abe Sutton highlighted the urgency of addressing these costs: “Drug prices in the US remain far too high. GENEROUS aims to ensure that Medicaid pricing will be on par with those in other developed nations. My hope is that all eligible Medicaid programs choose to participate in the pilot to help ensure that their Medicaid dollars can go further to support those in need.”
The model’s potential savings could redirect significant resources toward expanding healthcare services, improving care quality, and serving additional beneficiaries within existing budget constraints.
Stakeholder Participation and Next Steps
CMS plans to release a Request for Applications later this fall, inviting pharmaceutical manufacturers to participate in the program. Concurrently, state Medicaid agencies will receive invitations to submit letters of intent expressing their interest in participation.
States indicating interest will subsequently have opportunities to formally apply and potentially opt into the negotiated terms and pricing agreements established with participating drug manufacturers. This phased approach allows states to evaluate the program’s potential benefits before committing to participation.
HHS Secretary Robert F. Kennedy, Jr., emphasized the administration’s commitment: “Thanks to President Trump’s leadership and Dr. Oz’s bold direction at CMS, we’re expanding access to affordable medicines for millions of Americans. By bringing most-favored-nation pricing to Medicaid, we’re driving down drug costs and protecting the future of care for our most vulnerable citizens.”
Conclusion
The GENEROUS Model represents a bold approach to addressing pharmaceutical pricing challenges within Medicaid. By leveraging international price benchmarking and fostering manufacturer participation through standardized rebate agreements, the program aims to achieve sustainable cost reductions while maintaining medication access for vulnerable populations. As the program moves toward its 2026 launch, stakeholder engagement and participation levels will ultimately determine its success in transforming Medicaid drug pricing dynamics.
